I Letters Patent No. 85,691, dated Janna/r3 5, 1869.

. MPRO'VED SNOW-PLOW.

' The Schedule referred to in these Letters Patent and making part of the same.

To whom it may concern Be it known that 1, WILLIAM A. Pnnn'rz, of Iowa Falls, in the county of Hardin, and State of Iowa, have invented anew and useful Improvement in Railway Snow-Flows and Excavators; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings,

The shafts F are provided, at their rear ends, with pinions' G, driven by bevel-gears N on the upright shafts H, which are rotated by pinionsI, secured to them near their lower ends, which are, in turn, driven by the bevelgears J on a cranked shaft K, operated by any suitable steam-engine, secured at the rear end of the car. The engine may be supplied with steam from a boiler on the car, or by a flexible pipe from the boiler of the locomotive following it.

A cab, L, provided with lookouts, surmounts the being a part of this specification, in which- Figure 1 is a side elevation of my invention;

Figure 2 is a front elevation; and

Figure 3 is a detached elevation of the gearing for operating the same.

. Like letters refer to like parts in each figure.

The nature of thisinvention consists in providing a. railway platform-car with a double mould-board plow, at each side of which is an Archimedean screw, operated, through proper gearing, by a steam-engine at the rear'end of the car, the whole operating for the purpose of removing snow from railway-tracks.

To accomplish this end, I construct a proper car, the deck of which is shown at A, fig. 1, upon which I erect a double mould-board plow, B, to the forward end of which is attached a metallic apron, O, terminating near the level of the line of rails.

D are steps, secured to the apron, in which revolve the shafts F,-passing back, diverging, and elevated at an angle corresponding with the curve of the mouldboards, through which they pass, their rear ends supported by boxes or hangers pendent from the upper part of the plow.

Upon the shafts are secured Archimedean screws E, of long pitch, and tapered to conform to the channels of the mould-boards .in shape.

M. are guides, at the sides of the mould-boards, their direct the operation of the plow.

It will be seen that, as the car advances, the apron 0 takes up the snow, and the screws, revolving at a proper speed, will convey it to the rear ends of the channels in the mould-boards, and discharge it with ease and rapidity, at each side of the car, clear of the track What I claim as my invention, and desire to secure by Letters Patent, is

1'. The double mould-board plow B, provided with the apron O and curved guides M, constructed so as to be adapted to the screws E, substantially as and for the purposes set forth.

2. The screw-shafts F, screws E, steps D, upright shafts H, pinions G and I, bevel-gears N and J, and cranked shaft K, constructed so as to be connected with any suitable steam-engine, substantially as described, and operating for the purposes specified.

' 3. The combination and arrangement of the abovenamed parts with a proper car, A, and cab L, when constructed, arranged, and operating substantially as described, and for the purposes set forth.
